Blood
The structures of the male reproductive system that sperm do not travel through include Cowpter's gland and the seminal vessel
In earthworms, blood is pumped by a muscular blood vessel called the dorsal blood vessel. This vessel runs along the top side of the digestive tract and contracts rhythmically to circulate the blood throughout the worm's body.
The brainstem, specifically the medulla oblongata, regulates vasoconstriction through the autonomic nervous system. The sympathetic nervous system is responsible for increasing blood vessel tone through the release of norepinephrine, leading to vasoconstriction.
It wouldn't, unless you put it in a sealed and heated vessel and pumped most of the air out, creating a really low pressure..
The umbilical vessel removes urine from the bladder of the fetus via the kidneys. The umbilical vessel has many uses in the fetal/placental environment.
throbbing is when for example, your finger feels like it has pressure on it. It squeezes tight.
upper chambers of the heart
embolism
embolism is the sudden blockage of a blood vessel by an embolus.
The pulmonary vein carries blood rich in oxygen from the lungs to the heart. This oxygenated blood is then pumped to the rest of the body through the aorta.
Humans: blood enters the right atrium, collects, get dumped into the right ventrical, gets pumped to the lungs, collects in the left aurical (atrium), gets dumped into the left ventrical, guts pumped into the aorta (a blood vessel) and to the body! Figure it out.

The blood is pumped down the aorta and then into the renal artery. When the blood is deoxygenised, it is returned to the heart via the renal vein and later the vena cava.
Ballast tanks are compartments in ships or submarines that can be filled with water or emptied to control buoyancy and stability. When water is pumped into these tanks, the vessel's weight increases, allowing it to sink lower in the water, enhancing stability in rough seas or during loading. Conversely, when the water is pumped out, the vessel becomes lighter and rises, making it easier to maneuver or surface. This system is crucial for maintaining safe and efficient operation, especially in varying sea conditions.
the cardiovascular system delivers blood throughout the bodyThe cardiovascular system is a complex structure consisting of the heart as the main pump. The heart pumps blood to the lungs to be oxygenated. Oxygenated blood flows through arteries to areas around the body. De-oxygenated blood travels through veins back to the heart where it is pumped back to the lungs. Its a basic cycle.
In earthworms, blood is pumped by a muscular blood vessel called the dorsal blood vessel. This vessel runs along the top side of the digestive tract and contracts rhythmically to circulate the blood throughout the worm's body.
The aorta just as it comes out of your left ventricle.
