Joe is a 65-year-old man. Two years ago, Joe was driving home from the golf course when he had a heart attack. Joe's car struck a tree head-on, and he broke his left leg in the accident.

Bone tissue is repaired with lots of fibrosis; cardiac muscle has very little collagen. B. Only epithelial tissues and bone can regenerate;all other tissues are repaired with only fibrosis. C. None of these is relevant to the situation. D. Bone is good at regeneration; cardiac muscle has very little or no ability to regenerate. E. When bone tissue is damaged, there is no inflammation; cardiac muscle has lots of inflammation.
A. if someone (in the anatomical position) is hit in the knee by the front bumper of car coming from the left side of the person, which structure in the knee joint is the most likely to be torn? why? B. Sometimes in order to stimulate healing of the articular cartilage in the knee joint, a surgeon may have to induce bleeding by drilling a hole through the articular cartilage into the underlying bone. Explain why induced bleeding tends to help the healing process of the articular cartilage.
An 18-year-old high school football player suffered a torn anterior cruciate ligament (ACL) in the state playoffs. After undergoing repair, he found it difficult to ambulate with the knee brace. Weighing close to 140 kg (approximately 300 pounds), the athlete found it difficult to stand and balance on one leg. His mother was unable to support him by herself. After 1 week, the young man began to have increased pain and swelling in the calf of his affected leg. In the middle of the night, the teen called out to his mother, complaining of a shortness of breath and unexplained anxiety. His mother called 9-1-1, and he was taken to a local hospital. In the emergency department, he was diagnosed with a deep vein thrombosis and a pulmonary embolism. Oxygen and low-molecular-weight heparin were administered, and the young man was admitted to the intensive care unit. As a result of the thrombus lodging in the pulmonary circulation, the sympathetic nervous system is activated. Hemodynamically,…
