Answer:
El sistema respiratorio humano es una serie de órganos responsables de tomar oxígeno y expulsar dióxido de carbono. Los órganos primarios del sistema respiratorio son los pulmones, que llevan a cabo este intercambio de gases a medida que respiramos, otro órgano que nuestro sistema respiratorio tiene es el diafragma, el diafragma es un músculo esquelético delgado que se encuentra en la base del cofre y separa el abdomen del pecho, se contrae y se aplana cuando inhalas. Esto crea un efecto de vacío que atrae el aire hacia los pulmones cuando exhalas, el diafragma se relaja y el aire sale de los pulmones.
Red blood cells (erythrocytes)
The red blood cells are highly specialized, well adapted for their primary function of transporting oxygen from the lungs to all of the body tissues. Red cells are approximately 7.8 μm (1 μm = 0.000039 inch) in diameter and have the form of biconcave disks, a shape that provides a large surface-to-volume ratio. When fresh blood is examined with the microscope, red cells appear to be yellow-green disks with pale centres containing no visible internal structures. When blood is centrifuged to cause the cells to settle, the volume of packed red cells (hematocrit value) ranges between 42 and 54 percent of total volume in men and between 37 and 47 percent in women; values are somewhat lower in children. Normal red blood cells are fairly uniform in volume, so that the hematocrit value is determined largely by the number of red cells per unit of blood. The normal red cell count ranges between four million and six million per cubic millimetre.
The parts of a body can be compared to the parts of a house because:
All the parts of the house help the house stand up, and same with your body. All your bones help you stand up and walk around and get moving. This is how parts of a body can be compared to a house. Hope this helps!
After the first 12 hours, the body loses about 0.39°C (0.7°F) per hour. than 12 hours. you use the rate of 0.78°C per hour to estimate the time of death. Temperature of dead body is 32.2°C
