What are two methods of taking your pulse?
1. ankle & wrist arteries
2. radial & carotid arteries
3. carotid & atrial arteries
4. radial & bicep arteries

Answers

Ankle and wrist I wish it also had neck on there cause those are the most spots where they usually check ur pulse

Two methods of taking your pulse is 2. radial & carotid arteries.

Ankle & wrist arteries are not commonly used to take a pulse. The ankle pulse can be difficult to find accurately, and the wrist pulse is usually referred to as the radial pulse.

The radial pulse and carotid pulse are two common methods of taking a person's pulse rate:

Radial Pulse: The radial pulse is taken at the wrist, on the thumb side. Place your index and middle fingers lightly on the wrist just below the base of the thumb. You should be able to feel the rhythmic pulsations of the radial artery.

Carotid Pulse: The carotid pulse is taken at the neck, on either side of the windpipe (trachea), just below the angle of the jaw. Gently press your fingers against the side of your neck to feel the pulsations of the carotid artery.

Both of these methods allow for an accurate measurement of the heart rate. The radial pulse is more commonly used in non-emergency situations, as it is easier to access and less intrusive. However, in emergency situations, the carotid pulse is often checked because it is closer to the heart and can be easily felt in cases where the radial pulse might not be palpable.

our esteem-based needs are met by developing self-respect and achieving our personal goals.

Answers

Answer:

I believe so, yes.

Explanation:

If you have self-respect for yourself and really focus on the things you want to do in life, should result in higher self-esteem/esteem-based needs.

For example: Self-respect behavior

If you love yourself and acknowledge everything about yourself. You really just get to know yourself and have a deeper understanding of yourself. I think that is how you would achieve this. You don't go hating and making fun of yourself. You love yourself for who you are. ( P.S. I am no expert, so please take that into consideration. )

Another example: Personal Goals

If you push yourself hard enough and love yourself in the process, I think you will achieve great things. If you thrive and really accomplish the things you want in life. You have these goals no matter what others say about them. They are your goals for a reason. YOU want them, not other people. Just try to be optimistic about things, even when you don't feel like it.

What do proteins, carbohydrates, and fats do for your body?

Answers

Answer:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. Carbohydrates should be your body's main source of energy in a healthy, balanced diet. They're broken down into glucose (sugar) before being absorbed into your blood. The glucose then enters your body's cells with the help of insulin. Fat is a source of essential fatty acids, which the body cannot make itself. Fat helps the body absorb vitamin A, vitamin D and vitamin E. These vitamins are fat-soluble, which means they can only be absorbed with the help of fats.

Answer:

proteins help the body to grow and develop, carbohydrates provide energy and fats also give energy to the body and support cell growth
