These tiny chambers are called alveoli. They are not exclusive to just reptiles, but are part of the circulatory system of all vertebrates.
Endocardium
The membrane lining the inner surface of the uterus, or womb.
The inner lining of the intestine has folds in it so as to increase the surface are. This greater aids in the absorption of nutrients from the gut. The larger the surface area, the greater the rate of absorption.
The endothelium is the medical term meaning lining of the blood vessels, including those of the heart. It is continuous with the endocardium, the inner lining of the heart chambers and heart valves.
The ribbon-like folds on the inner lining of the mitochondrial membrane are called cristae.
Endocardium is the innermost layer of tissue that lines the chambers of the heart.
The innermost layer of the heart is called the endocardium. It lines the heart's inner chambers and valves, providing a smooth surface for blood flow. The endocardium is continuous with the endothelial lining of blood vessels, including arteries, veins, and capillaries, facilitating seamless circulation throughout the body.
Pericardium: visceral- lining organ, parietal-= cavity lining Epicardium- surface if the heart Myocardium- muscle wall, cardiac muscle Endocardium- inner lining- chamber walls
The membrane lining the inner surface of the heart is called the endocardium. It is a thin layer of endothelial cells that provides a smooth surface for blood flow and helps prevent blood clots. The endocardium also plays a role in the function of the heart's valves and is involved in regulating the contraction of the heart muscle.
Endometriosis are the pieces of the inner lining of the uterus are ectopic.
The ribbon-like folds on the inner lining of the mitochondrial membrane are called cristae.
The inner lining of the ventral (bottom) surface of the brain is called the meninges. It is made up of three layers - the dura mater, arachnoid mater, and pia mater - and serves to protect the brain and spinal cord.
