Answer:
Extensor muscles in the hind limbs of terrestrial vertebrates are typically bigger than flexor muscles because they serve an important function in supporting the animal's weight and allowing it to stand and move on land. The extensor muscles are in charge of extending the limbs and maintaining body posture against gravity, which takes a significant degree of strength and endurance. Flexor muscles, on the other hand, are in charge of bending the joints and raising the limbs off the ground, which takes less energy and strength. To successfully support the animal's weight and maintain its posture, the extensor muscles must be bigger and stronger than the flexor muscles.
What is a nonspecific defense?
What is the body’s second life of defense? When does it take effect?
Identify the roles of nonspecific leukocytes in the body’s second line of defense.
Jera cut her finger. The next day, the skin around the cut became red and warm. Why are these signs of infection?
A nonspecific defense, also known as innate immunity, refers to the body's general defense mechanisms that act against a wide range of pathogens.
What is a nonspecific defense?A nonspecific defense includes physical barriers such as skin and mucous membranes, as well as cellular and biochemical components such as leukocytes and complement proteins.
The body's second line of defense is also known as the innate immune response. It takes effect immediately or within hours after a pathogen enters the body. This response includes the activation of leukocytes, the production of cytokines, and the complement system.
Nonspecific leukocytes play several roles in the body's second line of defense. Neutrophils are the most abundant type of leukocyte and are the first to arrive at the site of infection. They engulf and destroy invading microorganisms through a process called phagocytosis. Monocytes, which mature into macrophages, also play a role in phagocytosis and produce cytokines that activate other leukocytes. Natural killer (NK) cells are lymphocytes that can recognize and kill virus-infected cells and tumor cells.
The redness and warmth around Jera's cut are signs of inflammation, which is a response of the body's innate immune system to injury or infection. Inflammation occurs when leukocytes and other immune cells are recruited to the site of injury or infection. The increased blood flow to the area causes the redness and warmth, and the accumulation of leukocytes causes swelling and pain. These signs indicate that the body's innate immune system is responding to the injury and attempting to prevent the spread of infection.

According to Mrs. Adams doctor’s order, she is to take 10 ml of sucralfate QID for her duodenal ulcers. If giving Mrs. Adams this medication using a teaspoon, how many teaspoons would you give her and how many times a day would you give this to her?
Answer:
Assuming that a teaspoon is equal to 5 ml, we can calculate the number of teaspoons to give Mrs. Adams as follows:
10 ml ÷ 5 ml/teaspoon = 2 teaspoons
Therefore, Mrs. Adams should be given 2 teaspoons of sucralfate four times a day (QID).
Isabella likes to meet with her friends in a park every morning for work to practice some yoga poses. She finds that it loosens
her up and gets her ready for the day. Even though her yoga may include more than one form of exercise, which type of exercise
is Isabella LEAST likely getting during these sessions?
Given that Isabella practices yoga in the park every morning, the type of exercise she is LEAST likely getting during these sessions would be cardiovascular exercise. Yoga typically involves slow and controlled movements, and while it can improve flexibility, strength, and balance, it is not considered a high-intensity cardiovascular workout. Isabella may be getting some level of cardiovascular exercise depending on the intensity of her yoga practice, but it is likely not the primary focus of her sessions.
