In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
Cat with chronic kidney disease and typical symptoms: fatigue, emaciation and dull, shaggy coat. The chronic kidney disease of the cat (CKD or CNE) – also called chronic renal insufficiency (CRI or CNI) or chronic renal failure (CRF) in the older literature – is an incurable, progressive disease characterized by a gradual decrease in the nephrons and thus to a decreasing function ...
The term "big cat" is typically used to refer to any of the five living members of the genus Panthera, namely the tiger, lion, jaguar, leopard, and snow leopard. [ 1 ] [ 2 ] All cats descend from the Felidae family, sharing similar musculature, cardiovascular systems, skeletal frames, and behaviour.
The short length of the digestive tract of the cat causes cats' digestive system to weigh less than other species of animals, which allows cats to be active predators. [31] While cats are well adapted to be predators they have a limited ability to regulate catabolic enzymes of amino acids meaning amino acids are constantly being destroyed and ...
The portal venous system is responsible for directing blood from parts of the gastrointestinal tract to the liver. Substances absorbed in the small intestine travel first to the liver for processing before continuing to the heart.
A countercurrent exchange system is utilized between the venous and arterial capillaries. Lowering the pH levels in the venous capillaries causes oxygen to unbind from blood hemoglobin because of the Root effect. This causes an increase in venous blood oxygen partial pressure, allowing the oxygen to diffuse through the capillary membrane and ...
The anatomy of the circulatory system in a living animal may be studied noninvasively via angiography, a technique in which blood vessels are visualised after being injected with an opaque dye. Other means of study include radiological techniques of imaging, such as X-ray and MRI.
