The functions of blood include transporting oxygen and nutrients to cells, removing waste products from tissues, maintaining body temperature, regulating pH levels, and protecting against infections through the immune system. Blood also plays a crucial role in clotting to prevent excessive bleeding.
Tissues with the best blood supply include the heart, lungs, liver, and kidneys. These organs require abundant blood flow to support their high metabolic demands and functions.
Avascular tissues receive nutrients through diffusion from neighboring blood vessels or surrounding tissues. These tissues depend on a close proximity to a blood supply to maintain their metabolic functions.
An organ performs more complex functions than the tissues that make it up could perform alone. Organs are made up of specialized tissues that work together to carry out specific functions, such as the heart pumping blood or the lungs exchanging oxygen and carbon dioxide. By combining different tissues with complementary roles, organs can perform more complex activities that individual tissues cannot achieve independently.
Blood and lymphatic vessels
Most tissues in the body are innervated, meaning they receive nerve supply from the nervous system. This includes muscles, organs, skin, blood vessels, and glands. Innervation plays a crucial role in controlling various functions and responses of these tissues.
Arterioles are small blood vessels that carry oxygenated blood to the body tissues.
They pump blood from the heart into the lungs or all the other tissues of the body.
Tissues with the best blood supply include the heart, lungs, liver, and kidneys. These organs require abundant blood flow to support their high metabolic demands and functions.
Yes, the partial pressure of oxygen (pO2) in the blood is what drives the diffusion of oxygen from the lungs to the tissues in the body. This oxygen is carried by red blood cells and released to tissues where it is needed for various cellular functions.
Blood vessels, including arteries, arterioles, and capillaries, deliver blood to your body tissues. These vessels carry oxygen and nutrients to cells throughout the body, allowing for essential functions and processes to occur.
Avascular tissues receive nutrients through diffusion from neighboring blood vessels or surrounding tissues. These tissues depend on a close proximity to a blood supply to maintain their metabolic functions.
Capillaries are the smallest blood vessels. They connect arteries and veins. They are the site of gas, waste, and nutrient exchange between the blood and the body tissues.
Connective Tissues Do
The circulatory system functions to transport nutrients and oxygen to tissues and cells throughout the body. It also removes waste products, such as carbon dioxide, from tissues back to the lungs for elimination. This system is comprised of the heart, blood vessels, and blood.
1. Arteries- takes blood away from the heart 2. Capillaries- exchanges oxygen with tissues 3. Veins- takes blood back to the heart
Arteries - carry blood away from the heart Veins - carry blood back to the heart Capillaries - allow the exchange of water/chemicals between blood and tissues
