Question

Amphicoelias fragillimus Discovered and studied in the late 1800s, Amphicoelias fragillimus is one of the largest known vertebrate species. The adult size is estimated to be 40-60 meters (130-200 ft) in length and 122 tons in weight. Based on anatomical estimates, the brain of A. fragillimus is 16 m above the heart, and their feet are 6 m below their heart when standing. Despite its massive size, it is assumed that all the physiological systems of the species are efficient such that they survived natural selection during Jurassic Period. hen standing., Despite its Design a circulatory system that allows for efficient bulk transport of blood to the tissues. 1,8 Meters (6 Feet) 58 Meters (190 Feet)

Explanation / Answer

3) Blood flow to all parts of the body is regulated by the blood pressure. But, this blood pressure surely affected by the gravitational force. Blood flow is partly by pressure and partly by gravity in the upper body parts. Whereas the lower body parts have more gravitational pull over the blood pressure. But, the veins will control the pressure afterwards. Thus, the gravity surely influences the cardiac output, arterial and venous pressures.

4) Amhicoelias fragillimus is a dinosaur and gaint reptile herbivores. This implies that the general circulatory system would be pulmonary in nature. But, when this turns out to be an aquatic species the circulatory system would be systemic in nature. Because the gill present in aquatic species follows unidirectional blood flow. But the blood is only oxygenated through lungs by the presence of two circulatory routes in these reptiles.
