Anatomy And Physiology Blood – FAQ
Blood’s primary function is to transport oxygen and nutrients to the cells while removing carbon dioxide and other waste products. It also plays a crucial role in regulating body temperature, pH levels, and protecting the body from infections through its immune components.
Blood is composed of four main components: plasma, red blood cells, white blood cells, and platelets. Plasma is a liquid that makes up about 55% of blood, carrying nutrients, hormones, and waste products. Red blood cells transport oxygen, white blood cells fight infections, and platelets assist in clotting.
Blood circulation involves the heart pumping blood through a network of arteries, veins, and capillaries. Oxygenated blood is delivered from the heart to the body through arteries, while deoxygenated blood returns to the heart through veins. The exchange of gases, nutrients, and waste occurs in the capillaries.
Red blood cells (RBCs) are responsible for carrying oxygen from the lungs to the tissues and organs and transporting carbon dioxide back to the lungs for exhalation. They contain hemoglobin, a protein that binds to oxygen and gives blood its red color.
The body regulates blood pressure through a combination of neural and hormonal mechanisms. The autonomic nervous system adjusts the diameter of blood vessels, and hormones like adrenaline and angiotensin help control blood volume and vessel constriction. The kidneys also play a role by adjusting the volume of blood through fluid retention or excretion.
