Answer:
Epididymis
Explanation:
From the testes, the sperms travel to the epididymis. These structures can be found resting on top of each testes. Fresh out of the testes, sperms are not yet matured and this is where the epididymis takes over. The sperm are stored here and this is where sperm matures. From here, the sperm moves into the vas deferens.
The right atrium receives the de-oxygenated blood from the body. From the right atrium blood passes to the right ventricle.
The right ventricle propels this de-oxygenated blood to the lungs though pulmonary artery, for oxygenation. The deoxygenated blood loses carbon-di-oxide and gains oxygen in the lungs. This process is called gaseous exchange.
After the gaseous exchange, blood becomes oxygenated. This oxygenated blood comes to left atrium of the heart through pulmonary veins.
From the left atrium blood comes to the left ventricle. Left ventricle sends this oxygenated blood through aorta and arteries to all organs of the body.
