Anatomy and Physiology. The term homeostasis is used to mean maintenance of static or constant conditions in the internal environment in the organism. Essentially all of the organs and tissues of the body perform functions that help to maintain these constant conditions. For instance, the lungs provide oxygen to the extra cellular fluid to replenish oxygen that is being used by the cells; the kidneys maintain constant ion concentrations and the gastrointestinal system provides nutrients WebFeb 9, · The anatomy and physiology is the study of the structures with in the body and how they function in the body.

Tissues in the body are made up of cells that are similar in structure and have a special specific function also different shapes and sizes. There are four different types of tissues the connective, muscle, epithelial and nerve tissue. Two or more tissue types that perform a certain function or functions grouped together make up an organ. A group of organs work together to ensure survival of the body by interacting and performing related functions that make up the body system, for example the cardiovascular system.
All the organs, cells, tissues and body systems working together make the organism that is a living thing. The levels of organisation in the cardiovascular system are related by working together to maintain the survival of the body. In a case that one of the cells or organs is not functioning properly it results to a breakdown in the whole system. The heart is a muscular organ; it is positioned in between the lung just to the left of the middle of the chest and behind the rib cage. It is roughly cone shaped hallow muscular organ.
It is about 10cm long and it is the size of a clinched fist. It weighed about grams in women and is a bit heavier in men which it is about grams. The heart wall is composed of three layers of tissues which are pericardium, myocardium and endocardium. The pericardium is the outermost layer and it is made up of two sacks. The outer sac consists of fibrous and the inner of a continuous double layer of serous membrane, the myocardium is composed of specialised cardiac muscle which can only be found in the heart. It is not under voluntary control but is striated like a skeletal muscle. The endocardium lines the chamber and valves of the heart.
It is a thin, smooth, glistening membrane that allows smooth flow of blood inside the heart. The structure of the heart and its associated blood vessels is shown in middle of the chest and behind the rib cage. The structure of the heart and its associated blood vessels is shown in Figure 1. The tallest Biology CHAPTER 32 The tallest tree is the Redwood Sequoia sempervirens approx m The tallest Angiosperm is the Australian Eucalyptus regnant Water Uptake and transport Fig. The heart has got four chambers. These four chambers are divided into two groups and each group has got two chambers.
These chambers are called the atria and the ventricles. The four chambers are related because they deliver blood to the heart. The upper chamber is called atria and it has fairly thin walls and dispatch blood through the veins. It works together with the right atrium, superior vena cava and the inferior vena cava to assist blood that is low in oxygen from various sites in the body. The coronary sinus is the smallest veins which can also drain blood into the right atrium, taking it from the wall of the heart.
Veins carry blood to the heart and with the exception of the pulmonary vein; they carry deoxygenated blood and waste carbon dioxide. The left atrium chamber of the heart receives blood from the lungs via pulmonary veins; two from the right lung and two left lung. Blood passes from the left atrium into the left ventricle through the atrioventricular opening, which is protected by a valve. The left ventricle has a very thick myocardium cardiac muscle which is needed by the blood receiving it from the left atrium into the aorta large artery and around the rest of the body.
The aortic valve is situated in-between the left ventricle and the aorta. Following to the decrease of the left ventricle, the valve closes and prevents back flow from the aorta to the left ventricle. Arteries carry blood away from the heart and with the exception of the pulmonary artery, the blood is oxygenated. Arteries consist of three layers of tissue. Tunica adventitia is the outer layer which consists of fibrous connective tissue. Tunica media is the centre layer which consists of smooth muscle and elastic tissue. Tunica intima is an inner layer consists of flat epithelial cells to ensure the artery lining is smooth and does not slow down the flow of blood. The heart pumps oxygen which rich blood to every living cell in the human body.
In order to do this it must beat continuously with none stop. The heart uses almost 2, gallons of blood. In order for the heart to deliver oxygenated blood to all the cells around the body and maintain the blood pressure in the lungs and general circulation, blood is pumped through arteries. The heart beats times a minute. the blood returns to the heart. Blood returning to the heart from all parts of the body, except the lungs, enters the right atrium, diagram of the heart showing all four chambers, and associated vessels and valves. Outline th way the heart beats and is heart prevents the oxygenated blood on the left side from mixing with the deoxygenate d blood on the right side.
The muscular heart pumps the blood Within the body they are different types of level of structural complexity. The most fundamental is chemical level. Gross anatomy entails the study structures that are seen through the naked eyes. On the other hand, microscopic anatomy encompasses the use of the microscope to explore the minute anatomical structure and is the histology field that studies the structure of tissues from cell biology to organs. Human physiology refers the study human bodily functions in good health, the cell and their organs of which they are composed. Most human physiology aspects are closely homologous to corresponding of animal experimentation and physiology has offered much of foundation of physiological knowledge.
Anatomy, Biochemistry the study of living structures chemistry and human physiology are complementary basic medical sciences, which are primarily taught together to students pursuing medicine. Excellent mastery of the knowledge on the human physiology and anatomy forms the basis of all medicine. Without knowing how the body is made up, how it can go wrong and how it works, we cannot even design the effective interventions and treatments, including new pharmaceutical drugs and surgery. Learning physiology and anatomy well mean that you know the general basics of medicine. The disease is a deviation from normalcy, and if you understand the normal function physiology and structure anatomy it is very easy to realise the origin of the problem.
Cellular functions results from chemical changes and the bodily functions depend on these cellular functions. In addition, anatomy helps in understanding the human body part structures. And the physiology study helps to know the functions of those parts that aid the organism in its action performance.
Human anatomy is the study of the human body structural features and is subdivided into histology and gross anatomy. Gross anatomy entails the study structures that are seen through the naked eyes.

Understanding human anatomy helps is discovering bodily malfunctions thus facilitating their correction. Human nervous system is a system that collects and transmits stimuli received from sensory receptors to the spinal cord and the brain and transmits feedback impulses back to the body parts. Humans being among the higher vertebrates, their nervous system consist of two crucial parts; the PNS and the CNS.
The peripheral nervous system consists of the nervous that originates from the spinal cord at the tributaries as well as the various level of the spinal column. Stuck with your essay?
