The respiratory system consists of the upper respiratory tract (nasal passages), the airway conduction system (larynx, trachea, bronchi, bronchioles, and terminal bronchioles), and the lower respiratory tract (alveolar ducts and alveoli). The primary organs of

Why are the kidneys considered major organs responsible for maintaining HOMEOSTASIS? The rat’s circulatory system is smaller in size.

A pair of pulmonary veins collect oxygenated blood from lungs and open into left atrium. A hepatic portal vein collects blood from various parts of alimentary canal and opens into liver (instead of heart). The circulatory system functions to deliver oxygen, nutrients, and hormones as well as transporting waste products.

the excretory system are the 5. This as well as their hemoglobin rich blood which is much better at making use of the little oxygen available to them, makes them well suited to survive in poorly ventilated tunnels that remain a relatively constant temperature. A pair of precavals or anterior vena cava collect the deoxygenated blood from the anterior region of the body and open into the right atrium.

An aortic arch arises from the left ventricle and supplies blood to all the parts of the body. The circulatory system includes the heart, blood vessels and blood, and is vital for fighting diseases and maintaining homeostasis (proper temperature and pH balance). 1. dorsal to the urinary bladder is the 2. Pulmonary circulation carries blood through the lungs for oxygenation and then back to the heart. (iv) Right internal mammary supplies blood to the muscles of the back Introduction. Use the rat circulatory system diagram to state the name of the large vessels that return deoxygenated blood from the heart to the lungs: _____ Related Documents. 2. The major reproductive 1.

Compare the location of the urethral orifice on male and female rats.6. horns are small lumpy glands called 1.What tube connects the kidney to the bladder? an environment for the developing embryo.1. different functions: the excretory system removes wastes and the reproductive (c) Anterior mesenteric vein collects blood from ileum Circulatory System. The right and left superior venae cavae return deoxygenated blood to the heart from the right and left side of the head and neck. The heart of the rat consists of four chambers. Locate the structures in your own rat and then observe the structures of the opposite sex from another group's rat.1. The thoracic cavity is drained by the azygous vein which empties into the left superior vena cava near its entry into the right atrium. (d) Posterior mesenteric vein collects blood from large intestine. The blood is pumped from the right ventricle through the pulmonary semilunar valve into the pulmonary trunk (usually colourless) which divides into right and left pulmonary arteries going to the lungs.
