papillary muscles
The interventricular septum separates the left and right ventricles. This muscular wall prevents the mixing of oxygen-rich and oxygen-poor blood.
The walls of the ventricles of the heart aren't thinner than the atria, they are thicker. This is because they require more power as they pump blood around the body, while the atria only pump blood the short distance into the ventricles. More muscular walls are therefore needed to provide this power which is why they are thicker. The left ventricle is even thicker than the right ventricle as it requires a lot more power to pump blood all around the body. The right ventricle only pumps blood to the lungs.
The heart has four chambers. The two ventricles (right and left) are muscular chambers that propel the blood out of the heart (the right ventricle to the lungs, and the left ventricle to all other organs). The two atria (right and left) hold the blood returning to the heart, and at just the right moment empty into the right and left ventricles...
the difference between the ventricles and the atria is that the ventricles are thicker
There are two ventricles in the pig heart
Fingerlike projections in the small intestine are called villi
fimbriae
stereocilia
A pair of tubes with fingerlike projections refers to the fallopian tubes in the female reproductive system. These tubes connect the ovaries to the uterus and are where fertilization typically occurs. The fingerlike projections, called fimbriae, help capture the egg released from the ovary and direct it into the tube.
It is the Villi
Villi
The pair of tubes with fingerlike projections that draw in the egg in female reproductive system are called fallopian tubes. They are responsible for transporting eggs from the ovaries to the uterus for fertilization.
Fingerlike projections that absorb nutrients in the small intestine are called villi. Villi increase the surface area of the intestinal lining, allowing for better absorption of nutrients into the bloodstream.
Projecting from the small intestine are microscopic fingerlike projections known as
Fingerlike projections of cytoplasm are known as pseudopodia. These structures are temporary extensions of the cell membrane that are used for cell movement, phagocytosis, and capturing prey in some organisms like amoebas.
The fingerlike projections that capture the freshly ovulated ovum are called fimbriae. They are located at the end of the fallopian tube and help sweep the egg into the tube after ovulation.
The villi are the tiny finger-like projections that cover the folds of the small intestine. The singular of villi is villus.
