The bladder can distend to store urine that eventually leaves through the urethra. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body. At the same time, the blood pressure will drop when the blood cells squeeze through the lamellae (see the respiration module), and the blood pressure that remains after the blood had passed through the gills has to be high enough to drive the blood around the body. The pump for the pulmonary circuit, which circulates blood through the lungs, is the right ventricle. Certain parts of the circulatory system present particular challenges to the body. low blood pressure in arterioles in the nephron; a decrease in fluid flow through the distal tubule Term The primary route for ion loss from the body is the __________ system. After oxygen is removed from the blood, the deoxygenated blood flows to the lungs, where it is reoxygenated and sent through the veins back to the heart.

Both oxygenated and deoxygenated blood consist of similar osmolarities, hemoglobin level, and salinity. through the tricuspid valve. BODY (HUMAN) HEAT TRANSFER. Contraction of the ventricle forces the blood into the capillary networks of the gills where gas exchange occurs. The left ventricle pumps the oxygen-rich blood to the body. The left ventricle ejects blood into the aorta, which then distributes the blood flow throughout the body using a network of blood vessels. The heart is a central pump that produces the force that causes the blood to flow through the body. The circulatory system is responsible for the transport of body fluids such as blood and lymph and for the temperature regulation. The first sound heard as the artery opens enough for the first pumps of blood to come through is known as the ‘systolic’ pressure. Step three is that blood is forced passed the tricuspid valve into the right ventricle. It is also involved in the removal of. Right side of the heart.
