What is in control of "twisting" the ventricular walls in order to squeeze out all the blood into the aorta or pulmonary trunk? Group of answer choices purkinje fibers AV nodes SA nodes pacemaker cells
Answer:
The correct answer is:
Purkinje fibers
Explanation:
The human heart is an organ, made up majorly of muscles called cardiac muscles, and is responsible for pumping blood throughout the body. The cycle of coordination of blood flow through the heart is known as the cardiac cycle and the process is coordinated by the cardiac conduction system.
The process starts with the sinoatrial (SA) node, also known as pacemakers, causing the generation of impulses that travel through the heart causing the contraction of the atrium (upper part of the heart). This impulse moves to the AV bundle (bundle of His), which branches out, spreading into enlarged fibers called Purkinje fibers. When the impulses reach the Purkinje fibers, it generates the contraction of the ventricular walls in a twisting motion, forcing blood into the aorta.

Which statement is true regarding blood transfusions? Blood transfusions were common practice in the seventeenth century. They routinely infused human blood into animals. Blood transfusions were performed by infusing sheep's blood into humans; in the eighteenth century, they were common and highly successful. In the seventeenth century, blood transfusions were rarely done and often fatal; they were outlawed until the nineteenth century. A blood transfusion is a lifesaving procedure that was developed and perfected in the nineteenth century.
Answer: In the seventeenth century, blood transfusions were rarely done and often fatal; they were outlawed until the nineteenth century.
Explanation:
In the 17th century, people began to speculate that blood transfusions could be done to save human lives especially after it was discovered that blood flowed forward not back and forth.
They used animal blood for transfusion however which resulted in it being fatal most times. This led to several governments in Europe issuing bans on blood transfusion and therefore making it illegal until the process dramatically improved in the 19th century.

when your injury has been iced and wrapped what do you do next
Answer:As soon as possible after an injury, such as a knee or ankle sprain, you can relieve pain and swelling and promote healing and flexibility with RICE—Rest, Ice, Compression, and Elevation.
Rest. Rest and protect the injured or sore area. Stop, change, or take a break from any activity that may be causing your pain or soreness.
Ice. Cold will reduce pain and swelling. Apply an ice or cold pack right away to prevent or minimize swelling. Apply the ice or cold pack for 10 to 20 minutes, 3 or more times a day. After 48 to 72 hours, if swelling is gone, apply heat to the area that hurts. Do not apply ice or heat directly to the skin. Place a towel over the cold or heat pack before applying it to the skin.
Compression. Compression, or wrapping the injured or sore area with an elastic bandage (such as an Ace wrap), will help decrease swelling. Don't wrap it too tightly, because this can cause more swelling below the affected area. Loosen the bandage if it gets too tight. Signs that the bandage is too tight include numbness, tingling, increased pain, coolness, or swelling in the area below the bandage. Talk to your doctor if you think you need to use a wrap for longer than 48 to 72 hours; a more serious problem may be present.
Elevation. Elevate the injured or sore area on pillows while applying ice and anytime you are sitting or lying down. Try to keep the area at or above the level of your heart to help minimize swelling.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may also help relieve your pain and swelling. They include:
Ibuprofen, such as Advil or Motrin.
Naproxen, such as Aleve or Naprosyn.
Be safe with medicines. Read and follow all instructions on the label.
When your soreness and pain are gone, begin stretching and strengthening exercises slowly, then gradually increase these exercises.
