C. The cardiovascular system is responsible for warming the muscles. The cardiovascular system brings heat from the heart to the muscles.

D. The cardiovascular system delivers carbon dioxide and glucose to the working muscles. It also takes oxygen and other wastes away.

Answers

Answer 1

Answer:A

Explanation:WILD GUESS

Answer 2

The cardiovascular system delivers oxygen and glucose to the working muscles. It also takes carbon dioxide and other wastes away is the main function of the cardiovascular system during physical activity. Correct option is A.

The main function of the cardiovascular system during physical activity is to deliver oxygen and nutrients, such as glucose, to the working muscles to support their increased energy demands. As muscles work harder during exercise, they require more oxygen and glucose for energy production. The cardiovascular system, consisting of the heart, blood vessels, and blood, works to transport oxygen and glucose from the lungs and digestive system, respectively, to the muscles.

Simultaneously, the cardiovascular system is responsible for removing waste products, such as carbon dioxide and lactic acid, from the muscles. These waste products are generated as a result of increased energy production during exercise. The cardiovascular system carries these waste products away from the muscles and delivers them to the lungs (for carbon dioxide) and other elimination organs for excretion.

In summary, the cardiovascular system plays a crucial role in providing the necessary nutrients and oxygen to the working muscles during physical activity while removing waste products to maintain proper muscle function and overall performance.

What is this type of heat movement where heat from the body is lost to the cooler air in the surrounding?

Answers

Convection is the type of heat movement where heat from the body is lost to the cooler air in the surrounding.

Convection is the flow of fluid that causes heat to be transferred from one location to another. Convective heat transfer, while commonly treated as a separate technique of heat transmission, incorporates the combined processes of conduction and advection.

Heat transmission between things happens through direct contact in conduction. Heat transport occurs inside the fluid during convection. Heat transmission in radiation happens via electromagnetic waves rather than particles. Heat transfer occurs as a result of temperature differences.

Water is heated despite being a poor heat conductor due to convection. When the pot is placed over a flame, the water at the bottom of the pot heats up. Because hot water is lighter, it rises, whereas cold water falls.

What is BMI for age and what are its uses?

Answers

BMI-for-age is a continuous metric that may be used to test children and teenagers aged 2 to 20 years for obesity, overweight, healthy weight, or underweight.

A person's body mass index is computed using their weight and height. The BMI is calculated by dividing the body mass by the square of the body height and is given in kilograms per square metre (kg/m2).

The BMI can be calculated using a table or graphic that shows BMI as a function of mass and height, with contour lines or colors for different BMI categories, and that may use alternative units of measurement (converted to metric units for the calculation).

The BMI is commonly used to determine how far an individual's body weight deviates from what is typical for a person's height. The National Institutes of Health revised US standards in line with World Health Organization criteria in 1998, decreasing the normal/overweight cut-off from 27.8 (men) and 27.3 (women) BMI to 25. This had the consequence of redefining nearly 25 million formerly healthy Americans as overweight.

why do turtles breath out of their butts

Answers

Answer: Limited room and no ribcage

Pls give me brainliest i had to research

Explanation: The possible answer to the question lies in the turtle's shell. The shell, which evolved from ribs and vertebrae that flattened out and fused together, does more than keep the turtle safe from bites. When a turtle hibernates, it buries itself in cold water for up to five months. To survive, it has to change a lot of things about the way its body works. Some processes, such as fat burning, go anaerobic - or without oxygen - in a hibernating turtle. Anaerobic processes result in the build up of lactic acid, and anyone who has seen Aliens knows that too much acid isn't good for a body. The turtle's shell can not only store some lactic acid, but release bicarbonates (baking soda to the acid's vinegar) into the turtle's body. It's not just armor plating, it's a chemistry set.

It is, however, a fairly restrictive chemistry set. Without ribs that expand and contract, the turtle has no use for the lung and muscle set-up that most mammals have. Instead it has muscles that pull the body outwards, towards the openings of the shell, to allow it to inhale, and more muscles to squish the turtle's guts against its lungs to make it exhale. The combination makes for a lot of work, which is especially costly if every time you use a muscle your body's acid levels go up and oxygen levels go down.

Compare this to the relatively cheap butt breathing. Sacs next to the cloaca, called bursa, easily expand. The walls of these sacs are lined with blood vessels. Oxygen diffuses through the blood vessels, and the sacs are squeezed out. The entire procedure uses little energy for a turtle that doesn't have a lot to spare. Dignity has to play second-fiddle to survival sometimes.
