Blood is a blood fluid with specific functions. Give examples of the functions of blood fluid in the animal body and explain how the animal body defends itself by against changes H+ ion concentration.

Blood is indeed a crucial fluid within the animal body that performs a variety of functions essential for sustaining life. Below are examples of the functions of blood in the animal body:
1. Transportation: Blood transports oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs for exhalation. It also carries nutrients from the digestive tract to the cells, and waste products from the cells to the kidneys, liver, and lungs for excretion.
2. Regulation: Blood helps in regulating body temperature by distributing heat produced in muscles and other tissues and maintaining water and electrolyte balance within the body.
3. Protection: Blood contains white blood cells and antibodies that help defend the body against infection. The clotting mechanism also prevents excessive blood loss when injuries occur.
4. Communication: Hormones and other signaling molecules transported in the blood mediate communication between different parts of the body to coordinate various physiological functions.
Regarding the defense against changes in H+ ion (hydrogen ion) concentration, this pertains to the body's maintenance of acid-base balance, which is critical for proper cellular function. The animal body has several mechanisms to regulate the concentration of hydrogen ions, including:
1. Buffer Systems: Blood contains several buffers, such as bicarbonate, hemoglobin, and plasma proteins, which can quickly absorb excess H+ ions or release them to maintain pH within a narrow range.
2. Respiratory Compensation: The respiratory system can alter the rate and depth of breathing in response to changes in blood pH. Increased CO2 levels (which can lead to increased H+ through carbonic acid formation) stimulate faster and deeper breathing to exhale more CO2 and reduce acidity. Conversely, if there is too little CO2, the respiratory rate can decrease to retain CO2 and increase acidity.
3. Renal Compensation: The kidneys help regulate hydrogen ion concentration by excreting H+ ions and reabsorbing bicarbonate from the urine. This process is slower than respiratory compensation but can result in long-term adjustments to maintain the acid-base balance.
The statement "Blood is a blood fluid with specific functions" and the subsequent discussion about the functions of blood and regulation of H+ ion concentration does not come from a direct source such as "Pocok, G and Richard, C. D." It appears to be a summary of general physiological knowledge that would be covered in many standard textbooks of physiology and biology. However, if you are looking for textbook references that might cover this material, you may consider:
- "Guyton and Hall Textbook of Medical Physiology" by John E. Hall. This textbook is a comprehensive source that covers many aspects of human physiology, including detailed information on the functions of blood and acid-base balance.
- "Human Physiology: An Integrated Approach" by Dee Unglaub Silverthorn. This integrates themes and principles across various levels of physiology, including the regulation of hydrogen ion concentration and the role of blood in the body.
As for "Pocok, G and Richard, C. D.," it appears as though there may be some confusion with the names or citation; however, similar information can also be found in the textbook "Human Physiology" by Gillian Pocock and Christopher D. Richards, which is a useful reference for understanding the principles of physiological regulation, including blood functions and acid-base homeostasis.
