Houston Community College General Biology 1407 Lab. Exam 2 - Part 2 Dr. Subha Venkat (13 points) Station 1: Identify the labeled structure on the heart model and give its function A. Right Atrium Function: receives deoxygenated blood from the body B . Aorta Function: The heart pumps blood from the left ventricle into the aorta through the aortic valve. C. Vena Cava Function: The superior vena cava is the large vein which returns blood to the heart from the head, neck and both upper limbs. The inferior vena cava returns blood to the heart from the lower part of the body. D. Left Ventricle Function: pumps blood through aorta to the entire body E . Right Ventricle Function: receives blood from right atrium and sends it to the lungs via the pulmonary arteries F. Left Atrium Function: receives fresh, oxygenated blood from lungs Station 2: Identify the labels on the lung model: (10 points) A. __________ Pharynx_________ B. ___________ Trachea_____________________________ C. ______________ Lung__________________________ D. ______________ Larynx__________________________ E. ________________ Bronchus________________________ F. ______________ Bronchioles__________________________

Station 3: Identify the structures on the kidney and the urinary system model. (10 points) A. ____________ Ureter______________ B. ___________ Renal Pelvis___________ C. ____________ Major Calyx_____________ D. ___________ Cortex_________________ E. _________ Renal artery___________ F. ___________ Renal Vein__________ Station 4: Identify the structures on the nephron model. (10 points) A. ______ Bowman’s capsule______ B. ________ Glomerulus____________ C. _______ Afferent arteriole_________ D. _______ Efferent arteriole____________ E. ____ Proximal convolutes tubule______ F. ______ Loop of Henle_____ Station 5: Identify the type of tissue - Bone (4 points) Function: Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues , calcium and phosphate storage, and harboring of bone marrow Station 6: Identify the type of tissue - Cartilage (4 points) Function: Cartilage connective tissue is important because it provides support, but is less rigid than bone. It also allows for some flexibility of movement, but has more stability than muscle. Station 7: Identify the type of tissue - Adipose (4 points)

Function: Adipose tissue acts as an insulating layer, helping to reduce heat loss through the skin. It also has a protective function , providing mechanical protection ("padding") and support around some of the major organs, e.g. kidneys. Adipose tissue is also a means of energy storage . Station 8: Identify the type of tissue – Skeletal Muscle (4 points) Function: Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. Station 9: Identify the type of tissue - Skin (4 points) Function: The squamous cell epithelium forms a barrier between the body and the exterior environment. These cells also provide protection for the underlying tissues. Station10: Identify the type of tissue – Tendon (4 points) Function: Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to another bone, while tendons connect muscle to bone.
